DETAILED DESCRIPTION

The technical schemes in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only some of the embodiments of the present application and are not all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without inventive effort are within the scope of the present application.

A foldable storage box disclosed in the present application includes a plurality of box body components and several first zippers. Each box body component includes several side walls and a sub-bottom wall. Each side wall includes a bottom edge and two side edges connected to two ends of the bottom edge.

The sub-bottom wall of each box body component is flexible and is connected to the bottom edge of a respective side wall.

Each of the first zippers includes a slider, a back stop and two zipper sides, the back stop is fixedly connected to back ends of the two zipper sides, and the slider is slidably connected to the two zipper sides.

In a joined state of the foldable storage box,

a) the box body components are joined by the several first zippers to form a storage chamber;

b) in a circumferential direction about a vertical direction, a pair of vertical edges joined to each other is formed between every two adjacent side walls that belong to the different box body components;

c) several pairs of bottom edges joined to each other are formed between pairs of adjacent sub-bottom walls that belong to the different box body components, and each pair of bottom edges is connected end-to-end to an adjacent pair of vertical edges; and

d) the two zipper sides of each first zipper are respectively connected to two sides of the pair of vertical edges and the pair of bottom edges that are connected end-to-end, and the back stop of the first zipper is fixedly connected to the corresponding pair of vertical edges or of bottom edges.

In a folded state of the foldable storage box, the side walls of each of the box body components are attached to each other, and the sub-bottom wall of each of the box body components are sandwiched between the side walls thereof.

With the implementation of the scheme of the present application, the side walls of the box body components have a certain support strength, so that in the joined state of the foldable storage box, the foldable storage box will not collapse. Specifically, each side wall may include a sheet, a wrapping edge and an elastic skeleton. The wrapping edge is wrapped around the edge of the sheet and is fixedly connected to the edge of the sheet, an annular mounting channel is formed in the wrapping edge, and the elastic skeleton is annular and is located in the mounting channel.

Unlike the specific embodiment in which the side wall is provided with an elastic skeleton, it is not necessary for the sub-bottom wall to be provided with an elastic skeleton due to the need for convenient folding. In other words, the sub-bottom wall is flexible, so that it can be folded by itself, facilitating the folding operation of the foldable storage box.

It can be understood that, although the sub-bottom wall is located at the bottom of the storage chamber in general use scenarios, in some other use scenarios, the foldable storage box of the present application may also be used upside down, and the sub-bottom wall is located at the top of the storage chamber in this case.

The box body components are connected to each other via the back stop, ensuring that the box body components are not separated and hinged to each other. That is, the two box body components connected to the back stop can freely rotate about the back stop and folded. The first zipper is used to detachably connect the pair of vertical edges and the pair of bottom edges between the box body components to form the storage chamber.

In the prior art, the side walls of the storage box are connected to each other via a film hinge, and the side wall and the bottom wall are detachably connected to each other via a zipper. Therefore, firstly, the position where the items are taken out is limited to the opening in the upper portion of the storage box; secondly, in order to facilitate the transportation or storage of the storage box, the bottom wall needs to be detached separately, but the corresponding detachment path is ring-shaped, so that when the storage box itself is large in volume, and the detachment operation is more difficult; and thirdly, since the bottom wall is not foldable and the shape of the bottom wall does not match the shape of the side walls, the bottom wall cannot be completely received between the superimposed side walls.

In the foldable storage box of the present application, since the first zipper is detachably connected to the pair of vertical edges and the pair of bottom edges, a user can join the pair of vertical edges and the pair of bottom edges of box body components by sliding a slider of the first zipper to close the first zipper, so that the foldable storage box is brought into a joined state, that is, forming a storage chamber. On the contrary, in order to enlarge the angle of taking out and placing items or take out and place items in more ways, the user separates the pair of vertical edges by sliding the slider of the first zipper or separates both the pair of vertical edges and the pair of bottom edges to fold the storage box, so as to facilitate folding of the box body components. For example, the box body components can be rotatably connected to each other, and each sub-bottom wall can be folded between respective side walls. That is to say, like the traditional storage box, the items to be stored can be placed through the opening of the upper end of the foldable storage box in the joined state. In addition, the user of the foldable storage box of the present application can also separate the pair of vertical edges or the pair of bottom edges by sliding the slider of the first zipper, and take out and place the items through an opening formed by the separated pair of vertical edges or of bottom edges. This allows the items in the middle or at the bottom of the storage chamber to be taken out more conveniently, thereby providing convenience for the user.

When the foldable storage box of the present application is in an empty state, the user can choose to disassemble the foldable storage box and then fold same. Specifically, by sliding the slider of the first zipper in the direction approaching the back stop, the foldable storage box is released from the joined state when the slider is slide to a position adjacent to the back stop, that is, the pairs of vertical edges and the pair of bottom edges are separated, and the box body components are free to rotate relative to each other. In addition, at this moment, the box body components are connected by the back stop. On the one hand, the adjacent box body components can not only be folded around the back stop, but also be twisted relative to each other, which is more convenient to position the respective side walls thereof. On the other hand, since the box body components cannot be completely separated from each other, the user does not need to worry about the loss of some of the box body components.

In addition, for the storage box in the prior art, in order to expand the volume thereof, the size of the bottom wall is usually larger than that of the side wall. If the size of the bottom wall is larger than that of the side wall, the swollen degree after folding will be further aggravated, which is not conducive to the development of the foldable storage box in the direction of larger volume. The bottom wall of the foldable storage box of the present application is formed by joining a plurality of sub-bottom walls, the sub-bottom walls are made of a flexible material in the present application, and the sub-bottom walls may be directly placed or placed between two different side walls after being folded. Therefore, in general, the bottom wall of the foldable storage box of the present application is easier to store and less likely to form a swollen structure. The folded form of the foldable storage box of the present application then has a more organized form and a smaller thickness, which is convenient for storage and transportation.

Embodiment I

As shown in FIG. 1 , a foldable storage box 10 includes two box body components 11. Each box body component 11 includes two side walls 17, a flexible sub-bottom wall 18, and a flexible sub-top wall 19. The sub-bottom wall 18 and the sub-top wall 19 are substantially triangular in shape. The sub-bottom wall 18 can be folded in half along an altitude perpendicular to a pair of bottom edges 14, and is sandwiched between the two adjacent side walls 17 in a folded state of the box body component 11. Two box body components 11 are joined by a first zipper 12.

A user slides the slider of the first zipper 12 to enable the joining of two pairs of vertical edges 13, the pair of bottom edges 14 and a pair of top edges 15, that is, to complete the joining and detachment between the box body components 11. In a joined state of the foldable storage box 10, the sub-top walls 19 are joined to form a top wall of a storage chamber, the sub-bottom wall 18 are joined to form a bottom wall of the storage chamber, and the side walls 17 are connected to one another to form four walls of the storage chamber in a circumferential direction about the vertical direction, thereby forming a sealed storage chamber to wrap stored items on all sides. In the folded state of the foldable storage box 10, the sub-bottom walls 18 and the sub-top walls 19, which are separated from each other, can be folded and stored between respective side walls 17.

In this embodiment, since the first zipper 12 is detachably connected to the pairs of vertical edges 13, the pair of bottom edges 14 and the pair of top edges 15, the user can join the two pairs of vertical edges 13, the pair of bottom edges 14 and the pair of top edges 15 of the two box body components 11 by sliding the slider 124 of the first zipper 12 to close the first zipper 12, so that the foldable storage box 10 is brought into the joined state, that is, forming the storage chamber. When an operation is to be performed in the storage chamber, the slider 124 of the first zipper 12 is slide to separate part of the pair of top edges 15 or to separate the pair of top edges 15 and part of the pair of vertical edges 13 to form an opening, through which items to be stored can be placed and taken out. When the foldable storage box 10 is in an empty state, the user can choose to disassemble the foldable storage box 10 and then fold same. Specifically, by sliding the slider 124 of the first zipper 12 in the counterclockwise direction of FIG. 1 , the foldable storage box is released from the joined state when the slider 124 is slide to a position adjacent to a back stop 121, that is, the pairs of vertical edges 13, the pair of bottom edges 14, and the pair of top edges 15 are separated, and the box body components 11 are free to rotate relative to each other. In addition, at this moment, the box body components 11 are connected by the back stop 121. On the one hand, the adjacent box body components 11 can not only be folded around the back stop 121, but also be twisted relative to each other, which is more convenient to position the respective side walls 17 thereof. On the other hand, since the box body components 11 cannot be completely separated from each other, the user does not need to worry about the loss of some of the box body components 11. It can be understood that the top wall formed by joining the sub-top walls 19 is not necessary, and the sub-top wall 19 of each box body component 11 can be omitted on the basis of this embodiment, so as to form a storage chamber in communication with the outside through an opening.

The bottom wall of the foldable storage box 10 of the present application is formed by joining a plurality of sub-bottom walls 18, the sub-bottom walls 18 are made of a flexible material in the present application, and the sub-bottom walls 18 may be directly placed or placed between two different side walls 17 after being folded. Therefore, in general, the bottom wall of the foldable storage box of the present application is easier to store and less likely to form a swollen structure. The folded form of the foldable storage box 10 of the present application then has a more organized form and a smaller thickness, which is convenient for storage and transportation.

Embodiment II

As shown in FIG. 2 , a foldable storage box 20 includes a pair of bottom edges, two pairs of vertical edges and a first zipper 22. Like Embodiment I, when the user assembles the foldable storage box 20 in the folded state, a first zipper side 27 and a second zipper side 28 can be joined only by closing the first zipper 22, and the box body components 21 on two sides of the two zipper sides (27, 28) can then be assembled without separately joining the bottom wall or the side wall of the storage chamber, so that the process of joining the foldable storage box 20 and the process of folding the foldable storage box are simplified.

On the basis of the concept of this embodiment, in a scheme including a plurality of first zippers 22, those skilled in the art may appreciate that two ends of at least one pair of bottom edges of the foldable storage box 20 are respectively connected to two pairs of vertical edges, and the back stop 26 of the first zipper 22 corresponding to the pair of bottom edges is fixedly connected to the upper end of one of the pairs of vertical edges.

Embodiment III

As shown in FIG. 3 , a foldable storage box 30 includes four box body components 31, one first long zipper 32 and two first short zippers 33. Compared with Embodiment II, the side walls 313 are connected to each other via the first short zipper 33 instead of via the film hinge in Embodiment II. A first long zipper side 322 and a second long zipper side 323 of the first long zipper 32 are both joined to a pair of horizontal edges and two pairs of vertical edges between two box body components 31. A first short zipper side 332 and a second short zipper side 333 of the first short zipper 33 are respectively arranged on the side edges of the side walls 313 and the sub-bottom walls 314 of adjacent box body components 31. The back stop 331 of the first short zipper 33 is located near a center of the first long zipper 32 over the edge of the sub-bottom wall 314. In this embodiment, the box body components 31 adjacent to the first short zipper 33 can be rotated about the center and folded, while the two box body components 31 adjacent to the first long zipper 32 can be rotated about the back stop 321 of the first long zipper 32 and folded. When folding and storing the foldable storage box 30, the side walls 313 can be folded in pairs to each other, and the folding effect is more organized than that of the scheme in Embodiment II.

On the basis of the concept of this embodiment, there also may be three, five and more box body components 31 of the foldable storage box 30, and the number of first zippers is one less than the number of box body components. The plurality of first zippers are divided into divided into a longer first long zipper 32 and shorter first short zippers 33 according to different lengths. In the joined state of the foldable storage box, the two ends of the pair of bottom edges corresponding to the first long zipper are respectively connected to two pairs of vertical edges, and the back stop of the first long zipper 32 is fixedly connected to the upper end of one of the pairs of vertical edges; and the back stop of each first short zipper 33 is located on the corresponding pair of bottom edges and close to a center of the pair of bottom edges corresponding to the first long zipper 32.

Embodiment IV

As shown in FIG. 4 , a foldable storage box 40 includes four box body components 41 and four first zippers 42. Each box body component includes one side wall 43 and one sub-bottom wall 44. Back stops 45 of the four first zippers 42 are arranged collectively. Compared with Embodiment II in which the number of back stops 26 is equal to the number of first zippers 22, the collective arrangement of the back stops 45 in this embodiment can avoid the separate arrangement of a back stop 45 for each first zipper, achieving the purpose of sharing the back stop 45 and reducing the production and processing costs. The box body components 41 can be rotated about the back stop 45. Since the flexible sub-bottom wall 44 of each box body component 41 is connected to the back stop 45, the side walls 43 of the box body components 41 can be more easily superposed together, so that the foldable storage box 40 in the folded state can have a more organized folding effect and is convenient for storage and transportation.

On the basis of the concept of this embodiment, the improvement disclosed in this embodiment can be summarized as: there are three or more box body components 41, and the number of first zippers 42 is equal to the number of box body components 41; each box body component 41 has one side wall 43 and one sub-bottom wall 44; and in the joined state of the foldable storage box 40, the pairs of bottom edges extend radially, and the back stop of each of the first zippers is located at a radiation center of the pairs of bottom edges.

Embodiment V

As shown in FIG. 5 , a foldable storage box 50 includes three box body components 51 and two first zippers 52. By closing the two first zippers 52, the three box body components 51 are joined to form a storage chamber, and on a bottom wall of the storage chamber, the pairs of bottom edges 53 joined by the two first zippers 52 are parallel to each other. Compared with Embodiment II, in this embodiment, there are a plurality of first zippers 52 for joining the pairs of bottom edges 53, which are parallel to each other. Optionally, in the joined state of the foldable storage box 50, the sliders of the two first zippers 52 are on the same side, and there are the same number of side walls respectively at two ends of the box body component 51 between the two first zippers 52. Such a structure allows the user to lift the box body component 51 between the two parallel first zippers 52 and pull open the two first zippers 52 at the same time. That is, a disassembly method of opening the first zipper 52 by operating the box body component 51 is provided, which is suitable for a scene where the volume of the foldable storage box 50 is relatively large.

On the basis of the concept of this embodiment, in the joined state of the foldable storage box 50, the pair of bottom edges 53 are all linearly arranged at the bottom wall of the storage box, and there also may be three or more pairs of bottom edges 53 which are parallel to one another.

Embodiment VI

As shown in FIG. 6 , with the closing of two first zippers 62 of a foldable storage box 60, three box body components 61 are joined to form a storage chamber. Side walls of the box body component 61 sandwiched in the middle are divided into two groups at two ends, one group at one end includes only one side wall, and the other group at the other end includes three side walls connected to one another via film hinges. Correspondingly, two pairs of bottom edges 63 are close to each other on the side close to the one side wall, and away from each other on the side close to the three side walls. Compared with Embodiment I, the box body component 61 in the middle of the foldable storage box 60 in this embodiment provides a visually differentiated arrangement, so that the formed shape of the two pairs of bottom edges 63 can be observed, and the user can recognize the position of the slider of the first zipper 62 in the joined state of the foldable storage box 60 through this information, and locate the slider more quickly for operation. This embodiment is suitable for scenes where there are more side walls and scenes where the slider needs to be concealed.

On the basis of the concept of the present embodiment, in the joined state of the foldable storage box 60, the side walls of at least one of the box body components 61 are spaced into multiple groups with different numbers, for example, one group has two side walls, and the other group has three side walls. When there are multiple side walls in each group, the side walls belonging to the same group are rotatably connected to each other.

Embodiment VII

As shown in FIG. 7 , each box body component 71 of a foldable storage box 70 further includes a sub-top wall 75. The sub-top wall 75 is flexible. Each side wall 74 further includes a top edge 743, and two ends of the top edge 743 are respectively connected to two side edges 742. The sub-top wall 75 of each box body component 71 is connected to the top edge 743 of the side wall 74 of the box body component 71.

In the joined state of the foldable storage box 70,

I) several pairs of top edges 73 joined to each other are formed between two adjacent sub-top walls 75 that belong to the different box body components 71, and each pair of top edges 73 is connected end-to-end to an adjacent pair of vertical edges; and

II) the back stop of at least one of the first zippers 72 is fixedly connected to the corresponding pair of vertical edges at an upper or middle portion of the corresponding pair of vertical edges, and the first zipper 72 is detachably connected to the pair of vertical edges and the pair of top edges 73 that are connected end-to-end.

In the folded state of the foldable storage box 70, the sub-top wall 75 of each of the box body components 71 is also sandwiched between the side walls 74 thereof.

Combined with the scheme in Embodiment I, it can be seen that the sub-top walls 75 are joined to form a top wall of a storage chamber, the sub-bottom wall are joined to form a bottom wall of the storage chamber, and five side walls 74 are connected to one another in a circumferential direction about the vertical direction, thereby forming a sealed storage chamber to wrap stored items on all sides. In the folded state of the foldable storage box 70, the sub-bottom walls and the sub-top walls 75, which are separated from each other, can be folded and stored between respective side walls 74. In addition, since the first zipper 72 is detachably connected to the pairs of vertical edges, the pair of bottom edges and the pair of top edges 73, the user can join the two pairs of vertical edges, the pair of bottom edges and the pair of top edges 73 of the two box body components 71 by sliding the slider 76 of the first zipper 72 to close the first zipper 72, so that the foldable storage box 70 is brought into the joined state, that is, forming the storage chamber. When an operation is to be performed in the storage chamber, the slider 76 of the first zipper 72 is slide to separate part of the pair of top edges 73 or to separate the pair of top edges 73 and part of the pair of vertical edges to form an opening, through which items to be stored can be placed and taken out.

Further, the foldable storage box 70 is provided with two sliders 76 capable of sliding relative to each other on one first zipper 72, forming a two-way open-end or close-end zipper that shares one back stop 21. The advantage of providing two sliders 76 is that, firstly, when one of the sliders 76 fails or gets stuck, the user can still close and open the first zipper 72 by sliding the other slider 76, so that this product has a longer service life than the general storage box that only uses a single slider; and secondly, when the user joins or folds the foldable storage box 70, the operation speed can be accelerated by sliding the two sliders 76 at the same time.

In other words, those skilled in the art may appreciate that, according to needs, in the joined state of the foldable storage box 70, the back stop of the first zipper 72 is arranged at the bottom wall of the storage chamber; and tails of the two first zippers 72 are connected and share the back stop.

Further, as shown in FIG. 7 , the side wall 74 of each box body component 71 of the foldable storage box 70 includes a bottom edge 741 parallel to the horizontal plane, side edges 742 extending from the bottom edge 741, and a top edge 743 connected to upper ends of the side edges 742 which are approaching each other. Each side wall 74 as a whole is shaped to be smaller at the top than at the bottom. In the joined state of the foldable storage box 70, the side walls 74 are arranged to be inclined to the bottom wall of the storage chamber and close to each other, and each side edge 742 of each side wall 74 and a respective side edge 742 of the adjacent side wall 74 are attached to each other to form an approximately tapered shape. When the foldable storage box 70 is subjected to an impact force from the outside in the joined state, the side walls 74 support each other to counteract part of the force, and provide certain protection for the items in the storage chamber. At the same time, the foldable storage box 70 in this embodiment has distinct upper and lower ends, so that it is convenient for the user to determine the orientation of the foldable storage box 70, which is convenient to use.

In other words, those skilled in the art may appreciate that, according to needs, in the joined state of the foldable storage box 70, the top edge 743 of the side wall 74 of each of the box body components 71 has a width smaller than that of the bottom edge thereof, and the side edges 742 of the side wall 74 of each of the box body components 71 are arranged to approach each other in a direction away from the bottom wall of the storage chamber.
